Why can't hot food be stored in the refrigerator

Hot dishes cannot be placed directly in the refrigerator mainly because it may cause the temperature inside the refrigerator to rise, increase the risk of bacterial growth, and affect the taste of the food. Putting hot food in the refrigerator will temporarily raise the temperature of the refrigeration compartment, which may affect the storage of other foods; At the same time, the prolonged exposure of food to dangerous temperature zones during the cooling process can lead to the growth of bacteria; In addition, sudden cooling may alter the texture of food.

Putting hot dishes directly into the refrigerator at high temperatures can cause a significant increase in temperature inside the refrigeration compartment in a short period of time. The refrigerator needs to consume more energy to restore its low temperature state, which may cause other refrigerated foods to temporarily remain in an unsafe temperature range. Temperature fluctuations can accelerate the spoilage process of some ingredients, especially dairy and fresh foods, which are more susceptible to this impact. The temperature range between 60 ℃ and 4 ℃ for food is called the danger zone, where most pathogenic bacteria rapidly multiply. The natural cooling of hot dishes takes a long time to pass through this range, and the refrigeration speed of the refrigerator is limited, making it impossible to immediately lower the food to a safe temperature. The design temperature of the refrigerator's refrigeration compartment is usually around 4 ℃, which cannot quickly cool a large amount of hot food. The slow decrease in the center temperature may form a bacterial breeding ground.

It is recommended to leave hot rice dishes at room temperature for no more than 2 hours, divide them into small portions to accelerate heat dissipation, and refrigerate them when the temperature drops below 60 ℃. Using shallow containers to spread out food, taking a cold water bath or ice water bath can lower the temperature faster. Reasonably control the amount of heat stored in the refrigerator at a time to avoid affecting the overall refrigeration effect. Pay attention to regularly cleaning the refrigerator and storing raw and cooked foods separately to ensure food safety.
